For me JL wins by virtually every measure. With the new seat on A350, it approaches BA F in quality/proposition.

Specifically, there is a reasonable drinkable red Bordeaux (not BA F quality, but better than BA J reds). Furthermore, the steak is cooked appropriately, slightly pink and completely edible/enjoyable. The new seat is really excellent and well thought through, and equivalent of QR Q Suites in my view.
